Application September 11, 1943, Serial No. 501,943

v 9 Claims.

vention are, to generally improve upon and simplify the constructions set forth in the above iden tiiied patents and cof-pending patent applications, to provide a ball cock which is practically noiseless in operation, capable of effecting a rapid dispersion of the water passing through the valve during a ilushing function and to effectively counteract and break any siphonic conditions which tend to draw contaminated water from the bowl and tank backwardly into the water supply line.

Further objects of my invention are, to provide a ball cock having a wide range of a'djustability,

capable of being readily assembled and installed and which will not tend to clog as a result of dirt, sand and sediment carried by the water passing through the valve.

A further object' cf my invention is, to provide a ball cock Whereinpractically all of the structural partsmay be advantageously made from plastics, thus providing a light-Weight, strong and durable structure which is rust proof and not subject to corrosion.

With the foregoing and other objects in rvView, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and illustrated in the accompanying drawing in which:

Fl'g. 1 is a top plan View of my improved. ball coc Fig. 2 is a vertical section taken on theline 2-2 of Fig. 1.

Fig. 3 is a horizontal section taken on the line 3--3 of Fig. 2.

Fig. 4 is a horizontal section taken on the line ll-l of Fig. 2.`

Fig. 5 is a horizontal section taken on the line 5-5 of Fig. 2.

Fig. 6 is a detail section taken on the line 6- of Fig. 2.

Fig. 7 is a vertical cross section taken through the center of a modied form of the ball cock.

Referring by numerals to the accompanying drawing, which illustrates a preferred embodiment of my invention, I0 designates the bottom of a toilet flush tank having an opening I l for a base fitting I2 and for a nipple I3 which connects the water supply duct I4 to said iitting.

Screw seated in tting I2 in vertical alignment with nipple I3 is the lower end of a pipe I5 which extends upwardly within the tank and this pipe, together with a slightly larger pipe I6 concentrically disposed about said pipe I5, provide a support for the valve housing hereinafter more fully described. i

The lower end of pipe IS, which functions as a hush tube, is rigidly secured in any suitable ymanner to base I2 with water outlet and air inlet apertures lII formed in the wall of said pipe I6, just above said base and arranged between and secured by cement, acetone or the like, to the pipes I5 and IB just below their upper ends, is a ring I8.

Formed in the wall of pipe I6 just below ring I8 are water inlet apertures I9.

The annular space between the walls of pipes I5 and I6, with the exception of vertical ducts 20, is lled with plastics or suitable self-hardening cement and the upper and lower ends of these ducts communicate respectively with the apertures I9 and I'I.

Rigidly secured to a lateral extension 2I of base I2, directly over an opening 22 in said eXm tension, is the lower end of a vertical pipe 23, open at both ends `and formed through the wall of said pipe, a lshort distance above its lower end, are water `outlet apertures v24 over which are positioned hoods ory deilect'ors 25 open at their lower ends.

The valve housing carriedy by .the upper ends of pipes I5 and I6 comprises a lower part 26 and upper part 21 and when the valve is assembled,

the meeting edges' ofthe two parts are permanently fastened by acetone, cement or, if the housing is formed of metal, by welding.

Lower part 26`is provided withan opening 28 slightly larger than pipe I 6 and the upper end of said pipe projects through this opening and terminates in a chamber 2S between the housing parts.

Depending from the underside of housing part around opening 28, is an integralskirt 30 and formed in the inner face thereof, in horizontal alignment with apertures I9, is an annular groove 3|. The inner face of skirt 30 below groovey 3l inclines inwardly, so as to deilect water from said groove toward the surface of pipe I6.

The upper-end of pipe I5 extends through-an opening formed in upper housing part 2l and is rigidly secured to said upper part in any suitable manner, preferably by means of a ring 32 of selfhardening material such as plastics or cement. If desired, pipe I5 may be screwseated in the upper part 21 and which arrangement simplies the assembly or disassembly of the parts.

Seated in the upper portion of pipe I5 is a nozzle 33, .the upper end of which provides a seat for a piston valve 34 which is arranged for sliding movement inthe upper portion of pipe I5.

A link 35 pivotally connects valve 34 to a head 3B, to which a float-carrying arm 31 is connected and said head being pivoted on a pin 3B seated in brackets 39 on top of upper housing member 21 (see Figs. 2 and 6).

The construction just described is very similar to a corresponding arrangement disclosed in my aforesaid co-pending patent application filed November 18, 1942, Serial No. 466,001, with the link 35, in the present case, taking the place of a toggle pin in said co-pending application.

Formed through the wall of pipe I5 just below the upper end of nozzle 33 and above ring I8, are upwardly inclined slots 40 which, when valve 34 is lifted from its seat, permit water to discharge from pipe I5 upwardly, out through the open, upper end of pipe I6 into chamber 29.

The housing composed of parts 21 and 28 has a short, lateral extension 4I, having a chamber 42 common to chamber 29 and depending from said extension is a skirt 43, in the inner face of which, near its lower edge, is formed an annular groove 44.

Formed through the wall of skirt 43 above groove 44 is a series of air inlet apertures 45 and concentrically arranged within said skirt is the open, upper end of pipe 23.

Spacing ribs 41 formed integral with the upper portion of pipe 23 are secured by cement or acetone to the inner face of skirt 43 and said ribs pass vertically across groove 44.

The threaded portion 48 of a rod 49 is screw seated in that portion of the housing above chamber 42 and said rod, which gradually increases in diameter, extends downwardly through an aperture 50 in the housing below chamber 4I, thence downwardly through pipe 23 to a point near the bottom thereof, just above outlet aperture 22 in extension 2I.

A head 5I on the upper end of this tapered rod enables same to be rotated and at the same time to be raised or lowered, thereby adjusting the position of said rod relative t the surrounding pipe 23 and outlet 22.

Projecting laterally from housing 4I is a short tubular stem 52 with a jet opening 53 leading from chamber 4I into said stem and connected to the outer end of the latter is a refill tube 54.

Air inlet openings 55 are formed through the wall of stem 52 at right angles to the travel of the jet of water from opening 53 to the refill tube (see Fig. 3).

When a bowl flushing function takes place, the float carried by arm 31 lowers within the tank thereby swinging head 36 on its axis and through link 35, valve 34 is lifted from its seat thus permitting water under pressure to discharge from pipe I through nozzle 33 and through the upwardlv inclined slots 40 into chambers 29 and 42 in the valve housing. A portion of this water passes through opening 28 into groove` 3I, which functions las an expansion chamber, thence downwardly over the surface of tube I6 and at the same time part of the water vfrom groove 3l passes through apertures I9, thence downward through ducts 2l) and finally out through aper tures I1 into the tank to replace the water discharged therefrom during the flushing function.

The water from chamber 4I iiows downwardly through aperture 5D and then divides with a part flowing downwardly through tube 23 around rod 49, while the other part flows downwardly bctween the ribs 41 over the outer surface of tube 23. During this latter action, groove 44 functions as an expansion chamber.

A certain amount of the water flowing downward through tube passes out through apertures 24 and this discharge, .as well as the discharge of water through aperture 22, may be regulated by raising or lowering the tapered rod 49.

The structure and functions just described provide for a very rapid dissemination of water entering and passing through the valve and eliminate practically all noises which ordinarily attend flushing operations.

The rapid and practically unrestricted flow of water from the chambers 29 and 4I is effective in decreasing the tendency of the ports and ducts to become clogged by sand, dirt and the like and if, under abnormal conditions, any clogging should occur, the housing comprising parts 21 and 28 may be readily removed from the upper end of pipe I5,'thus permitting ready access to all .parts of the valve for cleansing purposes.

By constructing the main parts of the valve from plastics or the like, deterioration, as a resuit of rust and corrosion, is eliminated.

The sucking of contaminated water from the bowl through the valve into the supply line, as a result of siphonic conditions. is prevented by the admission of air into the valve, through apertures 45, 24. 22, I1, 28 and 55.

In Fig. 7 I have shown a modified structure wherein the main housing comprising the parts 21 and 2B are devoid of the lateral extension 4I` the tube 23 and the adjustable. tapered rod 49.

Thus it will be seen that I have provided an anti-Siphonic ball cock valve which is simple in structure, inexpensive of manufacture and very effective in performingr the functions for which it is intended.

It will be understood that minor changes in `the size. form and construction of the various parts of my improved anti-siphonic ball cock valve. may be made and substituted for those herein shown and described without departing from the spirit of mv invention. the scope of which is set forth in the :appended claims.
